Title:
非同期レンジシフト機構と移動中レンジシフト制御システムとを有する２速トランスファーケース
Document Type and Number:
Japanese Patent JP6660728
Kind Code:
B2
Abstract:
A transfer case for a four-wheel drive motor vehicle includes a two-speed range clutch unit, a mode clutch unit, a power-operated actuation mechanism and a control system. The actuation mechanism includes an electric motor, a geartrain driven by the motor for controlling rotation of an actuator shaft, a range actuator assembly and a mode actuator assembly. The range actuator assembly functions to move a shift collar associated with the range unit in response to rotation of the actuator shaft. The mode actuator assembly includes a mode cam and a ballramp unit. The mode cam is rotatively driven by the actuator shaft for controlling the clutch engagement force exerted on the friction clutch by the ballramp unit. The control system controls movement of the shift collar during motive operation of the motor vehicle to permit on-the-move range shifting.
